@ Shay: Here is a thinkscript for IV and IV percentile for TOS. def vol = impVolatility(); def IV=vol*100; def hi = highest(vol,252); def lo = lowest(vol,252); def perct = (vol - lo)*100 / (hi - lo); AddLabel(1, Concat("52wk IV Percentile " + Round(perct, 2), " %"), Color.gray); AddLabel(yes...

Shay: You seem to be asking the group what your question should be? -- Typical reference to IV and IV percentile, relate to the "30 day" value by default. While it is also viable to reference specific time frames and strikes for IV; that is less common. For example IF you want the IV for...

rmorse: Amen!

"Tongue in Cheek": Lottery tickets are great in hindsight! (Hmm!!! perhaps I failed to answer appropriately!) Actually, if back-testing proves this a profitable strategy, then it seems worthwhile. -- I am trying to get a handle on how to evaluate similar non-intuitive trades. So, this is...

This discussion is specific to lower liquidity options only (NO SPY, AAPL, etc) Can someone point me to information that helps shed more understanding on the relatively large Bid Size and Ask Size, when the Open Interest and Volume are relatively low? See screen shot below for an example...

If you purchased the JAN5 weekly (9 DTE) 3.50 Strike for 50 cents, you are now profitable by 10 to 22 cents per contract, not counting your commissions. Current DELTA is appx-.84 (ITM). Pic below:

The values above are incorrect, correct the entries and try again. (pasting between incompatible applications -- try copying values from a plain text source) For example, the first PUT referenced above implies you own "10 0"? March 2016 700 strike puts and you paid $40 each for them. At a...

For those of you that trade options on securities, where your quantity of contracts is a high percentage of the open interest and/or volume, can you provide some insight on how you size the position (and manage the trade, multiple staggered entries...?, spread the trade across multiple strikes...

was straight-forward prior to ", and then have it essentially ..." AKA "catch this fart and paint it green!"

Trading typically incurs slippage due to Bid/Ask spread. If not careful and liquidity is too low, you lose some going in and you lose some going out. IF liquidity is adequate, you should be able to at least buy at the ask, and sell at the bid. Many times you can do better if liquidity is...

Today expiration series XOM Call option with strike at $75 will cost you about (Ask: 4.30), with underlying at 79.16: You are paying a premium (79.50 for a 79.16 value) ! You will lose money. These short term options may not be the ideal place for you to learn option trading. -- you may be...

Look again! XOM has no 75 strike Calls offered at 22cents! Post what you are really observing, and perhaps someone can help. Which expiration are you looking at?

BTW: Option trading looks deceptively simple to the un-seasoned. All too often, when I "think" I am somewhat "experienced", I find there is so much more to understand. A friend of mine once stated "There is a lot we do not know about the unknown!" I am still learning at a faster pace than I...

response to one statement: "So when i want to short an option i would ..." No! You should get your terminology correct, else you will have more issues. You CAN short (sell) an option, but I do not think you really want to be doing that at this point. I think you are interested (or should be...

Attempting to answer your first question above: "I would to like to know amongst other things is if an option (shorted) doesnt go my way can i hold out until the expiration date and just lose what i put in?" What do you mean by (shorted)? Shorting would "typically" mean Selling the option...

cashclay: There is specific information and then there is general information about option trading. What typically occurs in a learning process is to try to grasp the "general" before understanding the "specific" information. You may find it worthwhile to form your theory for "general", then...

Jim: What was your trade? If it was selling a call or put or selling a credit spread, the MAX profit potential is the money you received for that trade! Look at your account statement to see what you did, and what you received in credit! See here for an example of an "Account Statement" display...

Best practice for me was to create and maintain a Trade Journal in Excel to track all trades, so I know what I did and why. However, if you are managing winners at 50% max profits, you should (also) place your GTC exit orders as soon or simultaneous with your entries. 1st triggers OCO or 1st...

a few notes: "... because I wanted to be as accurate as possible ... " Then why not use the CBOE method (https://www.cboe.com/micro/vix/vixwhite.pdf) which is also partially used by TOS (they claim they do, I have not computed myself to confirm) for each Expiry. Note: for the 6DTE series, the...

Huh? Seems like you have a bug in either your data source or your parsing of it. You should not observe Open or Close that is higher than the High OR lower than the Low! I use Quandl and sometimes just yahoo and have not observed that issue. Post you source and error (with source data) and...
